COLLAPSIBLE-TUBE PASTE FILLERAND CLOSER? Application filed February 5, 1925, SeriaI'No. 6,914;

This invention relates to apparatus for filling commercial collapsible tubes or containers with such material as olntments,

selves and all kinds of pastes such'as are supplied. in tubes of the specified character.

It is primarily intended for the pharmacist in dispensing ointments, salves and the like from physicians prescriptions calling for small quantities of paste and'is capable manner, without loss or waste.

of practical operation on any desired'quair tity of pasty substance in an easy and rapid Another aim is'to provide means whereby different sizes of tubes can be filled with the apparatus by changingthe nozzle to suit.

These several aims and objects are attained by the novelconstruction and arrangement of parts hereinafter described and shown in the accompanying drawing, forming a material part ofthis disclosure, and in which Figure 1 is a partialside elevational, pan tial longitudinal sectional, View of a tube filling apparatus made in accordance with the invention.

Figure 2 is a transverse sectional-view taken online 22 of Figure :1.

"Figure 3 is an enlarged fragmentary view of the substance reservoir and its unsheathing sleeve. i

Figure 4- is a transverse sectional View taken on line 4t ofiFigure i Figure 5 is a similar view taken on line 5-5 of Figure 3. v t

Figure 6 is a. transverse sectionaliview, similar to Figure 4 but showing the reservoir in an open position.

Figure 7 is a fragmentaryside elevational view of the apparatus as used in shaplng andfoldingthe tube after filling.

Referring more in detail to the drawing, the numeral 10 designates the base of the apparatus which may be fastened by screws ll to any suitable supporting surface.

A body 12 is supported on a stand 13 msing from the base 10, this body being essentially horizontally disposed and containing a longitudinal bore 14 reduced at the front end, as at 15, and thereafter counterbored from the front as at 16. I

A bracket 17 provided with a flanged base is secured on the rear end of the body, this bracket being bored to slidably receivea plunger rod 18 of considerable length, which also slides in the reduced bore of Renewed Catcher 8, 1927.

Theirod' 18 contains a slot/or keyway 2O m dwaylin its length, in which is engaged the point of a screw 21, set in theibracket 17, to act as akey preventing rotationof the plunger rod. Y

At the extreme front end of the rod is secured :a piston or plunger 22,. held by screw-threads or other preferred means, 'whlchinay fit the counterbore. 16 to seat 7 the body, and is provided at its outer extend-y A ng end with a hand actuating knob 19.-

therein and is interchangeable withothers of different diameters. -Loosely'mounted on the rod 18, within the; bore 14 of the body, isajslidable collar 23 pressed normally outward against the shouldered front end of the bore byfa compression spring 24 coiled about the-rod and abuttingthe collar. c

vA recess 25, leading from the bore of the bracket 17, through its entirelength'permits aipin 26 to pass throughthe bracket, engage the collar23 and compress the spring when thearod ispressed forward to [cause such action; g I I I A socket 27 is held on the front of the body by screws or other removable means, this socket being provided with a thumb screw 28 intersecting the bore 29 "of the .s'ocket,;which is in register with thebore 14 of the body.

fA cylindrical reservoir 30, composed of two equal longitudinal sections, connected near one end by a'hinge 31, is fittedto engage in the socket 27 and may be clamped therein by thescrewQS, one end of the hinge abutting the outer end of the socket, at which time the inner end of the reservoir makes contact with the face ofthebody, it' I being nnderstood that the piston 16 is neatly fitted to the opening in the reservoir.

Anyv ointment, salve or pasty, substance 32 may be deposited readily in the reservoir ;when the walls are opened and separated, as shown in Figure 6,-wh1ch upon closing are inserted in the socket and secured by the screw 28.. a r

A tubular sleeve or sheath 33 *ispassed over the reservoir, confiningit in closed position, preventing separation of the reservoir walls this sleeve extending cir'cumjacent the reservoir from the hinge 31 to the outer end, and as shown in Figure 1, the outer diameter'of the sleeve is such as to" neatly lit within the open rear and f the realis ible tube 34 to be filled, which is drawn its full length over the sleeve and held there over by the fingers of an operator, it being understood that the tube is provided with a cap or cl0sure3a. to prevent extrusion of the entered substance.

In case of using tubes of largeror smaller diameter, the socket 27 is replaced with another of suitable size, as is the reservoir 30 and sheath 33, together with'a corresponding piston 22, to suit the diameter'of the tube to be filled.

The upper portion of the body 12 is shaped to present a bevelled anvil surface 35 and at the front thereof is a sharply angled surface 36.

A hand lever 37 having equally-angularly flanged elements 38 fitting the sides of the body, is pivoted on the screws 39, these flanges having arms 40 carrying a cross-bar 4 1, the upper edge of which is sharply bevelled. 7

After filling the tube it is placed on the anvil 35 and the lever 37 pressed there'over, squeezingthe open end of the tube into the shape of a wedge having ,a flattened edge extension 42.

Thereafter the flattened extension 42 is placed between the angular surface 36 and bevelled portion of the bar 41, at that time presenting an open space reeptive of the same, and upon depression of the lever 37, together with obvious manipulations of the tube, its flattened extension will be folded and securely crimped. As many folds as may be desired can thus be made. 7 Although the foregoing is descriptive of the improvements in considerable detail, many minor changes may be made without departingfrom the scope of the invention in its broadest aspect.

Having thus described my invention, including the manner of its operation and use, what I claim as new and desire to secure by Letters Patent. is

1. A tube filling apparatus comprising a stand having a raised elongated body containing a longitudinal bore, a bracket at one end thereof, a plunger rod movable in the bore of said body and extending through the bracket, said rod having an operating knob at its outer end, and a plunger at the other end, means in said body to elastically limit the stroke of said plunger,a socketon the opposite end of the body, a hollow cylinder split lengthwise to present two equal sections connected by a hinge, means to secure said cylinder in said socket, and a sleeve slidably engaged over said cylinder,

said plunger being movable in the cylinder to press material contained therein into a tube engaged over said sleeve.

2. A tube filling apparatus comprising a frame having a guide bore, a plunger rod slidable therein, meansto prevent rotation of said rod, a compression spring encircling said rod within a portion of the bore, a collar loose upon said rod incontact with said spring, a pin in said rod adapted to engage said collar at a definite point in thestroke ofsaid rod, a plunger carried at the inner end of the rod, and a tube receiving bracket engaged on said frame in register with said plunger. j

3. In a tube filling apparatus, the combination with a stand, and a manually operable plunger rod guided therein, of a bracket removably engaged on said stand in register with the plunger, a tubular reservoir composed of two equal sections hingedly connected at one of their longitudinal edges, means for securing said reservoir in said bracket, a cylinderical sleeve enclosing said reservoir over which a tube to be filled is drawn, and means to secure the sleeve the key-way, a pin in said rod to passv through the slot in the bracket, a collar.

loose on said rod against which said pin makes contact near the termination of its stroke, a spring in said stand to urge said collar outwardly against the bracket, a plunger on the inner end of said rod, a removable reservoir held in register with the path of said plunger, and a cylindrical sleeve enveloping said reservoir. 5. In a tube filling apparatus, the combination with a stand, and a manually operable plunger rod guided therein, of brackets on each end of said stand, guiding means for said rod carried by one of said brackets, split cylindrical container for material and a tube engaging meanscarried by the other bracket. said container carrying bracket being interchangeable, and a piston removably engaged on said rod to register with the tube filling means and passthrough said container.
